Problems solved by technology

However, there are also deficiencies in the current melting method production process: the whole synthesis reaction needs to be reacted for a long time at a higher temperature, and the energy consumption is large, and zinc stearate reacts for a long time in a molten state, which will cause a large amount of condensation. block, which affects the activity of zinc stearate and also increases the difficulty of subsequent processing

preparation example Construction

[0028] A preparation method of improved zinc stearate, comprising the steps of:

[0029] 1) Add deionized water into the reaction kettle and heat up to 30-40°C;

[0030] 2) under stirring, add stearic acid to the reactor and make it dissolve;

[0031] 3) Continue to heat up to 60-80°C, under stirring, add zinc compound and hydrogen peroxide into the reaction kettle, seal the reaction kettle, evacuate to a vacuum degree of 50-100Pa, react for 30-60min, wash the product with hot water, remove water into the pulverizer for pulverization to obtain zinc stearate.

[0032] In the present invention, the stearic acid is dissolved at a temperature of 30-40° C., and the zinc compound and hydrogen peroxide are added at a higher stirring speed, so that the zinc compound can be quickly and uniformly dispersed in the stearic acid solution, and The hydrogen peroxide catalyst can also quickly catalyze the reaction of stearic acid and zinc compounds, and make the reaction proceed at 60-80°C,...

Embodiment approach 1

[0043] Embodiment 1, a kind of preparation method of improved zinc stearate, comprises the steps:

[0044] 1) Add deionized water into the reaction kettle and heat up to 30-40°C;

[0045] 2) under stirring, add stearic acid to the reactor and make it dissolve;

[0046] 3) Continue to heat up to 60-80°C, under stirring, add zinc compound and hydrogen peroxide into the reaction kettle, seal the reaction kettle, evacuate to a vacuum degree of 50-100Pa, react for 30-60min, wash the product with hot water, remove water into the pulverizer for pulverization to obtain zinc stearate.

Embodiment approach 2

[0047] Embodiment 2 is the same as Embodiment 1, except that the mass ratio of the deionized water to the total mass of stearic acid and zinc compounds is 6-8:1.

Abstract

The present invention relates to a kind of production technology of zinc stearate, more specifically, the present invention relates to a kind of preparation method of improved zinc stearate. The method comprises the following steps: adding deionized water to the reaction kettle, heating up to 30-40°C; adding stearic acid into the reaction kettle under stirring and dissolving it; continuing to heat up to 60-80°C, Add zinc oxide and hydrogen peroxide, seal the reaction kettle, evacuate to a vacuum degree of 50-100Pa, react for 30-60min, after cooling down, enter the pulverizer for pulverization to obtain zinc stearate. The zinc stearate prepared by the method of the invention has the advantages of high activity, easy crushing, and fine particle size, and the preparation method has low energy consumption and environmental protection, and has very obvious economic and social benefits.

Description

technical field [0001] The present invention relates to a kind of production technology of zinc stearate, more specifically, the present invention relates to a kind of preparation method of improved zinc stearate. Background technique [0002] Zinc stearate is mainly used as a non-toxic stabilizer for polyvinyl chloride, a lubricating release agent for plastic products, a lubricant for cosmetics, a flatting agent for paint, and a softener, release agent, halogen absorber, and textile in the rubber industry. Waterproofing agent occupies a wide market at home and abroad. At present, with the promulgation of laws and regulations related to environmental protection and the strengthening of people's awareness of environmental protection, zinc stearate and calcium stearate are important raw materials for calcium-zinc stabilizers, and the market demand is further expanding. The research on their synthesis process also received much attention. [0003] The earliest production proc...
